Is there a pin-compatible replacement for CYH127-220UH?

SWRB1207S-221MT and SLH1207S221MTT share the same 12.5x12.5mm package and are likely pin-compatible, but this requires verification against the datasheet landing pattern and your PCB layout.

What risks should I check before replacing CYH127-220UH?

Key risks include higher DC Resistance (DCR) causing increased power loss, and ensuring the candidate's saturation current (Isat) is sufficient for your application's peak current.

CYH127-220UH Alternatives, Datasheet & Cross Reference | Shenzhen Hanxia Electronics Co., LTD

Reviewing replacements for the CYH127-220UH, a 220µH power inductor. Key considerations for alternatives include matching the 1.16A current rating, 12.5x12.5mm package, and verifying saturation current performance.

AI replacement insight

Electrical riskmedium

Higher DCR and unknown Isat require circuit-level validation.

Package risklow

Candidates share the same 12.5x12.5mm footprint.

Can it be replaced directly?

No direct drop-in replacement has been confirmed. SWRB1207S-221MT is a strong candidate but requires engineering validation of its saturation current and higher DCR.

Best replacement path

Use SWRB1207S-221MT or SLH1207S221MTT after verifying saturation current and accepting slightly higher power loss from increased DCR.

Main risk

Electrical performance degradation due to higher DC Resistance (DCR) and unverified saturation current (Isat).

Recommended alternatives

A form-fit alternate with matching inductance and current, but higher DCR. Requires engineering review.
